SFEGIFICATION forming part of Letters Patent No. 789,826, datedSeptember 29, 1903.

v Application filed April 18, 190 3. Serial No. 158,223. (No model.)

To all whom it may concern.-

Be it known that I, SAMUEL BUTLER, a cilizen of the United Kingdom ofGreat Britain and Ireland, residing at Westbury-on-Trym, England, haveinvented certain new and useful Improvements Connected with AntiskiddingDevices for Motor-Vehicles, of which the following is a specification,such as will enable others skilled in the art to which it appertains tomake and use the same.

This invention has reference to and arises out of my previous inventionfor applying .a chain-like band or belt to the tires of wheels toprevent skidding or side slipping of motorcars, cycles, and the like,for which I have applied for Letters Patent in the United States, SerialNo. 153,264., of April 18, 1903.

The invention consists, first, in making a special tire with a flat faceor tread having formed upon it an extra thickness of soft india-rubberover what is usual in general tire construction in order to form a bedfor my chain-like band or belt to'lie upon and into which it may be ableto insert itself, forming its own groove or recess either by its owngrip upon the tire or by the weight of the car or cycle.

Secondly, the object of my invention is to provide a means of throwingoff my chainlike band or belt or other device in case of it gettingslack from any cause, such as by puncture or by the leaking of a valve,and which slackness might cause skidding of the'tire. There isconsiderable danger to the working parts of a car if the chain, belt, orother device should come off on the inner side of the wheel. I thereforeprovide what I call a bridle, of rope, wire, or other suitable material,which I attach to the chain or belt at a suitable number of places, andafter the chain, belt, or other device has been put on the wheel and thetire inflated, causing it to get a tight grip on the tire, Ithen'tighten up my bridle by screws, rings, or other suitable means. Iput this bridle on the outside of the wheel only, in which case shouldthe chain or belt become slack the bridle will pull it off the tire andonto the ground, and so save damage to the tire by running upon it whendeflated. The bridle will also save the chain or belt from dying intothe air should any part of it break. My bridle may be formed in a numberof waysybut I give herewith drawings of a few of the more simple ways inwhich it can be applied.

I will now describe my invention with reference to the accompanyingdrawings, in which Figure 1 shows a cross-section of a pneumatic tire 6with a fiat periphery to which my invention is applied. This tire hasinner tube g and is mounted on rim h of a Wheel. a a are the links of achain or belt placed on the tire forming a tread for the wheel, saidlinks being joined together by rivet-s or pins 17 b. tis a lug orprojection formed on a link of the chain and having a hole a, throughwhich is passed a wire rope Any suitable number of these lugs maybeused. A ring w, having wedge or cotter m, embraces the two parts of therope, which is capable of being ened by the said ring and wedge.

Fig. 2 shows a side view of Fig. 1 and more tightclearly shows thecotters or wedges w a; driven into the rings w to prevent the rope frombecoming slack.

Fig. 3 shows a side view of a portion of a tire e with inner tube 9 andmounted on rim h of a wheel. A modified form of my invention is appliedto this tire, the rings w and wedges so being dispensed with and anendless wire hoop 10 used in place thereof A chain or belt similar tothat shown in Figs. 1 and 2 is used on this tire. The rope o is passedalternately through the lugs 25 on the chain or belt and through thehoop, the ends of the rope being made fast by any suitable means, suchas an ordinary tightening-screw. (Not shown.) Should the chain or beltcome off the tire, it will fall onto the ground on the outside of thewheel, and thus be clear of the same and of the axle or driving-gear. Inplace of lacing the bridle in this way through an iron hoop I may use awire-rope hoop with means of tightening it andfasten the bridle-ropes toit by clips bolted or otherwise fastened to it at the points where therings or cotters are used in Fig. 2.

Fig. 4 shows a section of a tire c with another form of my invention asapplied to a belt of any suitable flexible material with metal pieces orplates riveted thereto to form a tread on which the wheel runs. :In thisfigure, i is a flexible belt, to which metal plates 10 19 are attachedby riveting to washers g by rivets k. 7 is a lug formed on plate 8,which is substituted at intervals for the washers q and in which is ahole 9 for the rope o. z is a hook on bracket 11 secured to the rim h ofthe wheel.

Fig. 5 is a side View of Fig. 4 and shows part of a tire and rim of awheel with the rope or bridle in the form of lacing passing alternatelythrough the lugs 7 and hooks z.

In the case of the belt coming 01f it will fall clear of the hooks z andwill be free to fall onto the ground.

It is obvious that my bridle may be applied in many other similar ways,so that the drawings must only be taken as showing examples of itsapplication.

What I claim, and desire to secure by Letters Patent, is-- 1. In avehicle-wheel, a tire, a chain having lugs projecting from its outeredge, a flexible connection run through the lugs, guides attached to thewheel through which the connection is passed and means for hold-' ingsaid connections against movement.

2. In a vehicle-wheel, a tire, a chain having lugs projecting from itsouter edge, a flexible connection run through the lugs, guides attachedto the wheel through which said connection is passed and means in theguides for holding the connections against movement.

3. In a vehicle-wheel, a tire, a chain having lugs projecting from itsouter edge, a flexible connection run through the lugs, guides attachedto the wheel through which the connection is passed and wedges in theguides frictionally engaging the connection against movement.

In witness whereof I have hereunto set my hand in presence of twowitnesses.

SAMUEL BUTLER.
